1998 sl500 secondary air pump
My mechanic informed me I need a secondary air pump at a cost of 1,255.00. Before I buy the pump, I want to replace the fuse (easy enough) and the relay to see if that gets the pump working. I’m going crazy trying to find where the relay is on a 1998 Sl500. Can someone help me find it?
